As jordan said, this is a worst-case scenario stress test, applying full braking power in an overweight landing situation. The brakes would not react this way under anything approaching normal circumstances. Yes, the brakes caught on fire, but the important thing is they can still stop the plane under those conditions. You can always evacuate the plane if you have to once it's on the ground and stopped.
@@belakarpati You can do the math on the kinetic energy, it's just 1/2mv². For an overweight landing, assuming the maximum takeoff weight of 575,000kg, and a very high landing speed of 150knots(77 meters/second), you get 1/2 * 575000 * 77² = 1704587500 joules, or 1704MJ. Given the A380 has 20 tires on its main gear, 1704/20 = 85.2MJ on each tire, much lower than their test of 125.2MJ. They also mention the speed being 90m/s. The maximum landing weight of the A380 is 386,000kg, and speed around 135 knots(69,45 meters/second, nice) is typical. 1/2 * 386000 * 69.45² = 930897382 joules, or 46MJ per tire. The most important thing to note though, is that this is assuming that the brakes are the **only** thing stopping the aircraft. In reality the speed brakes (flaps on wings) and reverse thrust does the majority of the braking under normal circumstances. I'm not so familiar with the A380, but if I had to bet I'd say that in the vast majority of landings the brakes dissipate less than 2MJ of kinetic energy per tire. 125.2MJ is a truly insane number and would likely never be reached in even the worst emergencies.
@@Stewi1014, Almost everything you said is true, except for the spoilers (it's called "Spoilers" when used for landing, and "Speedbreaks" when used in the air, for several reasons like increasing the rate of descent without gaining so much speed, for example).

Brakes are supposed to convert kinetic energy into heat energy. The wheel stopped, so this works. I mean seriously, you could ease up on the brakes and avoid the fire if you have the space. If you don’t have the space, it’s nice to know the brakes will work, even if they catch fire in the process.
I'd say the fire makes this MORE impressive, seeing it maintain braking performance at that sort of temperature. Granted, they're completely fried afterward but the plane is also stopped. I'd wager very few vehicle disc brakes can continue functioning while red hot or even approaching ignition, and none while managing that much energy
But all to say isn’t suspension supposed to use the conversion of kinetic energy into heat energy to help dampen the bumps??? And brakes are made simply to HELP slow the plane.
@@dillonlittlejohn4821 Slowing the plane is different to smoothing the bumps - yes suspension has damping, but it acts in the vertical direction. Braking is by far what primarily reduces the plane's horizontal speed.
@@dillonlittlejohn4821 The dashpot also converts kinetic energy to heat - but the amount its converting is much lower than the brakes - FAA says they have to withstand a descent of 600foot per minute landing, which is 5.83 knots. the A380 lands at 130 or so knots, and kinetic energy 1/2mv2 - so you have 500x as much energy to dissipate in the brakes vs the suspension.

For reference, a kilogram of tnt is about 4.184 megajoules of energy. So those brakes just absorbed the heat equivalent of roughly 30 kilograms of TNT exploding.
Back in the early 1980's I was a design engineer for Reliance Electric (now Rockwell Automation). I designed a regenerative DC drive system exactly like this application for the Boeing 747. Inertia of that flywheel was incredible (that's the flywheel the tire is riding on). I think it was a couple of hundred horsepower drive and DC motor. It had to have emergency braking to stop in case there was problem. Primary braking was regenerative braking so you could stop it as fast as you could accelerate it. That was easy. But Boeing also wanted resistive dynamic braking in case the regen braking failed. Imagine the resistor setup to dissipate that amount of flywheel energy in resistive heat. It required several full 80-inch-tall sections of big ass braking resistors. I still remember that one.
@@michaelbeary No. Capacitors only hold a very low amount of energy compared to regular batteries. The weight of eg. a lipo required to store that amount of energy, is too heavy to make it worth having onboard; the losses are higher than what it would save. The energy expelled here is 125MJ or 35kW/h. Those 35kW/h are expelled in 14 seconds, that's 9 megawatts. At an energy density of 0.2kw/h per kilo of lithium polymer battery, that's 174kg to hold 35kW/h (for comparison, electrolytic capacitors have an energy density of 0.2W/h per kilo, a thousandth). You can't charge a battery that fast though, so in order to charge at a safe rate, lets say 5C (standard is 1C), or 5kw per kilo, we need 1800kg, +25% since we cant charge fast near full capacity, 2250kg. Once you add a robust casing, perhaps liquid cooling, very heavy gauge wiring, alternator (realistically well over 1 ton) and the electronics for charging, we arrive at 4000kg minimum. Then there's the other 21 wheels to consider, too; 88 tons (would be 4 kiloton of capacitors). According to the stated fuel efficiency of the A380, it requires 3300 liters of fuel to carry an extra 88 tons just 100km. At 12kWh of energy per liter of jet fuel, that's 39600 kW/h or 39 megawatt hours of energy spent, to save 770 kilowatt hours of energy (assuming a short trip of 100km); in other words, you spend 51 times more than what you saved, in the best of circumstances; with capacitors, you'd be spending 2300 times the energy you'd save. That's all ignoring how extremely expensive it would be, and that the batteries would have to be replaced every ~500 cycles.

That's not what you'd be smelling. The brakes are stacks of carbon disks, it's called a "heat well" (as in water well) and that's what's burning. It's designed to work like that. They are fully contained in the tire hubs so the flames (and heat) escape away from the tire. I don't think anything on Earth has brakes anywhere near as powerful as airliners.

Its the danger inherent in commercial aerospace, you have very very long product development cycles, so you need to try and predict future market desires years if not decades in advance. The A380 was first studied in 1988, and announced in 1990 to compete with the 747, a vastly successful aircraft at the time that has since suffered a similar drop in market demand as the A380 (Boeing is stopping production in 2022)

When I was a little boy I heard of a new double deck plane. The Projectname at this time was Airbus A3XX. Now I‘m 35 years old. Yes. The A380 is that old. Airbus had after the 380 the A 350 and the A320 Neo…
Half the comments here are on the actual freaking awesome brake test, the other half on how old the video is. All I can say is, this is why max weight high speed braking tests are exciting
@@Cavemannnnnn @SalmqN one joule is one watt second. So 3,6 million watt seconds are one KWh. The total energy here was 125 Megajoule. This are 125 million watt seconds. If you divide 125 million / 3. 600.000 you get 34,7 kWh
In my previous job here in the U.K I made the disc brakes for the A380 along with the boeing 777 and 767 and F18 and F22. We made the segments and then shipped them to Honeywell to finish the process. My two brothers still work there.
I’ve got a job interview in 7 hours that I’m barely prepared for. I’ve never been on a plane in my life but here I am watching this and considering searching for more videos like it.
Whenever I start exploring new territories on youtube, the algorithm gets scared of the unusual new taste of mine and throws me this video on the home page for days to give me a hard detox.
Incredible how they heat up so much but don't melt and the rubber compound doesn't break or burn or anything similar. Airplane brakes are way more powerful than I remembered.
This would occur in a really catastrophic landing. In that case there would be fire trucks on standby dousing the plane as soon as it touches down. This video is basically worse than a worst case scenario.
This is why an aircraft cannot just "try it again" after doing an aborted take off. They have to go back to the gate and have the brakes cooled off or they may not be able to abort a second time. Besides that, hot brakes can cause the blow out plugs on the tires to let go while they are closed up in the landing gear compartment. Then you're landing on flat tires which can be dangerous. That's exactly what happened to me on a 747 flight New York to Saint Marten around 1980. I have the photos.
It was said that their brakes are powerful enough to stop the plane without any reverse thrusters. Those 2 out of 4 is just a secondary assist for best case scenario & on wet runways.
Yeah, it's on fire; after fully doing it's job well outside it's intended or stated parameters; and, still did the job. Yeah, they really do engineer the good stuff.

it actually started to dig harder when the fire started... that's crazy impressive that they can pour enough gas out of the assembly to keep it operating in those conditions
@@erikarneberg11 watch the joint in the fixture, you can track deflection that way because the housing is mounted solid. that's the assembly they use to track breaking force. once the flame start, you can see the force actually increases as the deflection increases. most automotive applications get what's known as "brake fade" where the heat generated creates a vapor barrier between the friction material and the rotor. this does the opposite, once it gets some real heat to it, it bites the rotors harder. so on a graph, most brakes would have a bell shaped curve if you plot stopping force vs temp, whereas these seem more like a line going up

You’re probably that guy who overestimates numbers
these "youtube recommendation" comments are sooooooo retarted
Crazy to think about the fact that "me at the zoo", the oldest video on CZcams was made only a year before this video
is the a380 that old?
@@carguye. Seems only yesterday! And it's production line is already being stopped!
When I was a little boy I heard of a new double deck plane. The Projectname at this time was Airbus A3XX. Now I‘m 35 years old. Yes. The A380 is that old. Airbus had after the 380 the A 350 and the A320 Neo…
one the first videos on yt ever watched by me was by some rapping guys from my home town xD --> czcams.com/video/DEd_Pj2uHV8/video.html
Finally, the relevant past comes to me! Algorithms, thank you from the bottom of my heart!
me too!!
Actually a most wonderful video I've seen on CZcams in past few years.
Half the comments here are on the actual freaking awesome brake test, the other half on how old the video is. All I can say is, this is why max weight high speed braking tests are exciting
If you covered too both halfs where does you're comment fit in?
@@ThexXxXxOLOxXxXx I'd say it's definitely on the first half, although meta on the second lol.
Brakes are so simple and powerful. This is the equivalent of a 5000kw engine.
no meaningful use of the power.
a politician perhaps.
Just stop
I would like to see the full size of that inertia drum that's being pushed on by the wheel. Imagine balancing that beast.
And imagine NOT balancing that, what a disaster video this would make.
"It only needs to survive 1 emergency stop."
I could have charged my Smart Ed3 nearly twice with this energy😅
yes, around 35 kWh in total
@@simonm1447 I'm curious. how did you calculate this?
@@Cavemannnnnn @SalmqN one joule is one watt second. So 3,6 million watt seconds are one KWh.
The total energy here was 125 Megajoule. This are 125 million watt seconds.
If you divide 125 million / 3. 600.000 you get 34,7 kWh
@@simonm1447 Thankyou :)
@@simonm1447 i dont understand a single thing that u wrote :/
In my previous job here in the U.K I made the disc brakes for the A380 along with the boeing 777 and 767 and F18 and F22. We made the segments and then shipped them to Honeywell to finish the process. My two brothers still work there.
I literally thought it was gonna explode and cover the whole screen with an explosion.
''THANK YOU FOR FLYING RYANAIR''
You know you've seen every video on CZcams when they start recommending videos from 2006...
hahaha
It's 14 years. And CZcams still recommends it. Wow 👏
Every 4 years YT thinks I should watch this again. And as always, I nevr regret it.
One of the first videos on CZcams! And I'm watching this in 2021!
14 years later CZcams is like o that’s a good video to recommend
these "youtube recommendation" comments are sooooooo retarted
at 3 am
Nobody asked you Robert
I’ve got a job interview in 7 hours that I’m barely prepared for. I’ve never been on a plane in my life but here I am watching this and considering searching for more videos like it.
Best of luck to you.
How did it go?
Did it go well?
you never been in a plane ok its gonna be a little scary but evrywone has that and once you in the air its fine being in a plane is fun 😊
Also interesting in knowing how it went. Did you find any good videos?
CZcams: "Hey! Wanna see a Airbus A380 brake test?"
Me: "Sure. why not?"
I love this. Great brakes
An oldie but a goodie! Thank you, oh great CZcams Algorithm of mystery, for recommending this again in 2021.
@Carson Anna what
This was a test to see if the brakes brake without breaking while baking.
Ha
I noticed this was a fact and a rhyme
Whenever I start exploring new territories on youtube, the algorithm gets scared of the unusual new taste of mine and throws me this video on the home page for days to give me a hard detox.
Incredible engineering! Making flying safer. Thank you 🙏🏻
Pretty sure this only makes landing safer
Landing doesn’t require brakes, if you want to nitpick. They are only applied after the plane has touched down 😄
This is probably the oldest video that I've seen in CZcams. Thanks recommendations
Here is THE oldest video posted by CZcams co-founder Jawed Karim. czcams.com/video/jNQXAC9IVRw/video.html
@@tomcat2285. there actually used to be videos older than me at the zoo but they got removed
I don't know what's more impressive the way the tyre held out or the amount of comments pointing out it's just been recommended 🤔
Shop clerk: "You need to replace your break pads.... and your breaking habits."
This has to be one of the coolest videos I've ever seen. Amazing.
That video of your mom was pretty good, too.😊
I like how someone is trying to convince us the A380 would already be over 15 years old.
Wait a second, it actually is. Omg how time flies 😵
What? did you think that time was swimming?
@@Finat0 it runs, it crawls but sometimes it flies lol
14 years later and this is in my recommendations
see y'all in another 14 years
That test is lit!
Incredible how they heat up so much but don't melt and the rubber compound doesn't break or burn or anything similar. Airplane brakes are way more powerful than I remembered.
Ah yes, this is what i wanted to see today.
A reminder that 2006 was FIFTEEN YEARS AGO.
Scary though...
I saw this video when it was first out on youtube! It's one of the first you-tube videos I ever saw.
After 17 years, my recommendations have shown this
I'm impressed that stopped it that fast.
I remember watching this video when I was 7 - 8 now I'm 18 damn the memories
Same here I was like that young and now I'm 19 😳 CZcams really understands nostalgia
Thanks youtube for recommending this blessing 14 years later
Yes bro
that was cool! love when companies show the engineering that got them where they are
Sounds like an awesome introduction to a hawkwind song!
This is amazing, it stopped the damn thing and it was crazy haha.
But that must be the most tense 45 seconds during that stop if it's ever needed.
This would occur in a really catastrophic landing. In that case there would be fire trucks on standby dousing the plane as soon as it touches down. This video is basically worse than a worst case scenario.
Rip sir..!! 👀😢
How has the decade been treating you so far?
Are you alive
@@alesyatlanc man he only commented doesn't mean he is dead and this comment is only 14 years back not 140 years
That's a lot of energy
@@AnIdiotAboard_ Not gonna lie, that initial number looked way more impressive before you made that comparison with the lightbulb xD
Walks into NAPA" I need new pads and rotors for a AIRBUS A380".
What a fantastic recommendation after 14 years =)
This is why an aircraft cannot just "try it again" after doing an aborted take off. They have to go back to the gate and have the brakes cooled off or they may not be able to abort a second time. Besides that, hot brakes can cause the blow out plugs on the tires to let go while they are closed up in the landing gear compartment. Then you're landing on flat tires which can be dangerous. That's exactly what happened to me on a 747 flight New York to Saint Marten around 1980. I have the photos.
I'm gonna leave my comment footprint here, so I can reply to myself after 14 years.
I’m going to leave my reply to your comment so I can reply to your reply of your comment in 14 years
Don’t forget
@@PHO3N1X_28 See you after 14 years brother, good luck soldier.
Just think, in 14 years (hopefully) this virus won’t be a thing, (hopefully) the world will be a better place
Good luck to you to! 🇬🇧
In 14 years there will be 500 answers witch is full, so yoh cant comment under your comment anymore.
See you after 70 years later brother.
That’s the longest run way ever. Good job
It was said that their brakes are powerful enough to stop the plane without any reverse thrusters. Those 2 out of 4 is just a secondary assist for best case scenario & on wet runways.
That is a *lot* of energy all in one place. And for some reason, I kind of like the sound it makes.
that's fine.. the sound is really satisfying especially knowing that the brake managed to stop the plane
14 years later and it pops up on my recommendations. Thank you CZcams.
Yeah, it's on fire; after fully doing it's job well outside it's intended or stated parameters; and, still did the job.
Yeah, they really do engineer the good stuff.
I can bet you those parts aren't made in China.
The water: Ayo bro cool down. Chill
Ahh yes the Airbus A380 brake test. It's nice to see it every once in a while. (and hear it)

it actually started to dig harder when the fire started... that's crazy impressive that they can pour enough gas out of the assembly to keep it operating in those conditions
???
@@erikarneberg11 watch the joint in the fixture, you can track deflection that way because the housing is mounted solid. that's the assembly they use to track breaking force.
once the flame start, you can see the force actually increases as the deflection increases. most automotive applications get what's known as "brake fade" where the heat generated creates a vapor barrier between the friction material and the rotor. this does the opposite, once it gets some real heat to it, it bites the rotors harder. so on a graph, most brakes would have a bell shaped curve if you plot stopping force vs temp, whereas these seem more like a line going up
And, after 14 years, this is finally recommended to me. 😂

This was 17 years ago
I remember working on the Tarmac and some planes would have their brakes glowing red when we brought it in to the gate.
It's incredible how they're able to accurately simulate the ground using a giant wheel.
It's amazing to think that these are what bring a several-ton-weighing aircraft to a stop
dont you mean a 560 tonne aircraft in regards to the A380
@@peanuts2105 Yeah, that's several tons worth of weight
@@Finat0
It's not several, it's many tons.
@@user-dv7hq2rh4g yes sry, bad wording on my part
Consider this awesome fenomenum: that massive amount of kinetic energy is transformed and absorbed by this litle piece of metal.
exactly. The coherent motion of 10^31 atoms going 200 mph is transformed into some number of carbon atoms randomly vibrating at 6,000 mph.
Over 5 million watts of energy transferal, or nearly 7000 braking horsepower. No wonder the fire...
This brought back rug burn memories for me for some reason

Why did get recommended 17 years later
And why did it just blow up after 17 years
“The smoke means it’s working.”
“Sir, it’s on fire..”
“Nah I’m telling you Jones, the fire is the best part!”
“Sir, when the plane touches down it still has hundreds of litres of fuel onboard! I assure you, as cool as it is, fire is definitely not a good idea!”
